The far, far away castle is pretty impressive and I'm sure a themed hotel like that inside an American park would be very successful, but they shouldn't go crazy. The Asian parks have it about right with how they use Shrek, but I think Dragon, Panda, and Madagascar are way more interesting.
A third park with DreamWorks, Nintendo (it seriously needs a bigger footprint than Kidszone allows), possibly Fantastic Beasts and Where to Find Them, could be really, really cool and possible game changer in the dynamics of central Florida theme parks. Am I forgetting an IP?
